I am an MS student at POSTECH GSAI (Graduate School of AI). I am currently doing research at the Interactive Machine Learning Lab advised by Prof. Kwang-Sung Jun.
My research interests lie in Statistical learning theory, Interactive machine learning, and the algorithmic foundations of machine learning algorithms. I am especially drawn to problems where mathematical structure can be used to make learning systems more reliable and provably correct.
Alongside my research, I am deeply interested in software engineering and passionate about building products that deliver real-world impact. In line with this commitment, I am was building a service KnowGem, a knowledge-graph workspace for hallucination-free reasoning over documents.

Research & Projects
|
A focused workspace that turns scattered documents into a navigable graph context and validates reasoning outputs with Higher-Order Logic. Aims to enable hallucination-free, deductive reasoning grounded in symbolic structure.
|
|
A clean, from-scratch PyTorch implementation of PPO compatible with the Gymnasium API, supporting both discrete and continuous control.
|
|
A portfolio-optimization system that learns allocation policies with PPO under diverse simulated market regimes, served through a FastAPI training/evaluation UI.
